To avoid the riskof fire, explosion, orasphyxiation from carbonmonoxide, NEVER operatethe water heater unless it isproperly vented and hasadequate air supply forproper operation asoutlined in the Ventingsection of this manual.WARNING: Use 3”/5”UL approved Category IIIStainless Steel ventmaterial only. No othervent material is permitted.WARNING: Refer topage 7 for clearances tocombustible material.Numberof 90°elbows(bends)MaximumLength ofStraightPipe1 26’(8.0 m)2 24' 6"’(7.5 m)3 23"(7.0 m)4 21' 6"(6.5 m)2’(61 cm)Max.VentingThe installation of venting must complywith national codes, local codes and thevent manufacturer’s instructions.The water heater must be vented to theoutdoors as described in these instructions.DO NOT connect this water heater to achimney. It must be vented separately fromall other appliances.All coaxial vent components (adapters, pipe,elbows, terminals, etc.) should be UL 1738Certified Stainless Steel Venting Material(e.g. AL29-4C).The specified vent termination must be used.(Refer to pages 13 and 14 for an example ofthe concentric vent.)Use the screws provided to connect thecoaxial vent pipe with the anti-disconnectionjoint.Follow coaxial vent manufacturer’sinstallation instructions and theirrecommended clearances to combustibles.The unit can be vented either horizontallyor vertically.Coaxial vent pipe runs must be adequatelysupported along both horizontal and verticalruns.The maximum recommended unsupportedspan should be no more than five (5) feet(1.5 m). Support isolation hanging bandsshould be used. DO NOT use wire. (Seediagram below).Venting LengthsMAXIMUM VENT LENGTH: Thesystem will not operate if there is excessiverestriction (pressure drop) in the ventingsystem. A maximum 26’(8.0 m) of vent pipemay be used provided there is only one 90°elbow in the system. If additional elbows arerequired: two elbows can be used with 24’6"(7.5 m), three elbows can be used with 23’(7.0 m) or four elbows can be used with 21’6" (6.5 m) of vent pipe.A 90° elbow is equivalent to 1’6” (.5 m) ofstraight pipe. A 45° elbow is equivalent to9” (.25 m) of straight pipe.The vent termination does not count asstraight pipe when determining total ventlengths.94° ElbowFireStop7/8" per footdownward slopeVent PipeWall PlatesNotes on pre-existing vent:NO!YES!If the water heater is being installed as areplacement for an existing water heater, athorough inspection of the existing ventingand air intake system must be performedprior to any installation work. Verify that thecorrect materials, vent lengths and terminallocations as detailed in this Use and CareManual have been met. Carefully inspect theentire venting and air intake system for anysigns of cracks or fractures, particularly atthe joints between elbows or other fittingsand the straight runs of vent pipe. Check thesystem for signs of sagging or other stressesin the joints as a result of misalignment ofany components in the system. If any ofthese conditions are found, they must becorrected in accordance with the ventinginstructions in this manual before completingthe installation and putting the water heaterinto service.See the back page of this manualfor additional requirements for theCommonwealth of Massachusetts.The 94° elbow is equivalent to a 90° elbow.The vent should be installed with a slightdownward slope of 7/8” per foot ofhorizontal run toward the vent terminal (seediagram below). This ensures that anycondensate formed during operation of theunit is evacuated from the appliance and toprevent rain from entering the appliance.An upward slope toward the vent terminal isnot acceptable for horizontal venting.MINIMUM VENT LENGTH: The ventingmay be as short as 12” (30 cm), providedone vent termination is installed to theoutdoors through a sidewall, one 94° elbowis included in the installation and the wallplates are installed.Notice: Make sure that the seam of the innervent pipe in horizontal runs is toward thetop of the installation (see diagram to the farleft).Vent SeamCeilingBoardInspectionAccess Panel #1InspectionAccessPanel #29AP14558-1 (09_08) DV 66 Manual.indd 99/17/2008 3:07:54 PM
